Resolves: rhbz#966051 Revert "1.48"
bouncycastle, bouncycastle-mail and bouncycastle-tsp all
have to be at the same version. If bouncycastle is bumped
to 1.48 then bouncycastle-mail 1.48 requires a new build
dependency package of "bcpkix" to be available first
This reverts commit 3750535f316da77b966942871d43a3f49c137e11.
